Awesome! Props on joining the club. I have been VERY happy with my M4. You will enjoy yours no doubt.

I am personally going to be running an IC Trulock flush mount choke. The reason for this is that out to 25-35 yards, OO buck will pattern well with this choke, and beyond that I will use slugs. The IC choke is arguably the best for slugs as while like Duggan said, Full won't hurt the barrel/choke, it WILL screw a slug up and hurt accuracy past 30 yards or so. With todays slugs, 10" groups at 100 yards from an M4 is very do-able from what I understand (I have kept them all on a pie-plate area at 50 yards off-hand). When I go with my mini-dot setup I plan on making the most of the weapon platform. 0-100 yards I want to be 100% effective. Will be keeping 4 slugs on the buttstock in a Mesa Tactical shell holder and the tube full of OO buck. The way the benelli action works, I can slip a slug in any time I need the extended range.

I too would like to know. For my optic I am going with a Larue throw-lever low-pro mount and a Pride/Fowler mini-dot sight. Allows change of the battery without removing the optic from the mount, on/off as well as automatic brightness, and the Larue throw-lever will allow QD and re-attatchment with a high level of precision.

I called Larue and then the Pride/Fowler company. Cody @ Larue was polite, and spoke confidently of the Larue mount. I have not heard ANYTHING bad about Larue in 5 years on AR15.com. That is impressive in and of itself. I e-mailed the Pride Fowler company asking about recoil and battery life capabilities of their sight. I have not yet checked my inbox. If Larue sells it though, I bet its g2g.

I think I found my optic http://stores.homestead.com/Laruetactical/Detail.bok?no=68 http://www.rapidreticle.com/sopscauto.htm I like this because: It is QD via a lever and I can revert to irons IMMEDIATELY for whatever reason. I do not have to remove the sight from the base to replace the battery. (Thus my zero is maintained) It is under $500 : ) It has an on/off so I do not have to rely on automatic brightness,although it features it as well.

When I can fire the weapon and have it jam on demand vs. firing the weapon and being UNABLE to jam it, I call that a problem with the stock spring. Thus I replaced it with another "stock" spring, albeit from another model. Maybe Benelli should have standardized the springs for their 7-shot tubes. WOuld have made more sense than introducing another part # to the catalogue.

I went with the stock Benelli M1 S90 spring b/c I am a sucker for OEM stuff and have NEVER heard of an M1 S90 having issues.

Using tactics that minimize their exposure to stray fire works well. Firing from the kneeling up to chest/neck on an assailant will keep your kids safe unless they are jumping on the bed or you are Yao Ming II's dad. Also keep in mind where they are in the house. (Don't shoot/set up where their room is your backstop).

Using that logic, after 10K rounds my M1 S90 spring will be = to an M4 spring. I like it. It did go from 35" to 31" in a quick fast hurry though.

Fun stuff, I am still in LS1 world being a college student and all. 01 WS6 m6 Yes, mine did not function with the M4 spring and the long tube and hotter 3" buckshot rounds. With 00 Buck 3" it did fine 90% of the time, but with the 3" #4 buck, which kicks a lot harder (for whatever reason, I have not calculated weight/velocity and all that jazz), it would not cycle. The inertia of the gun moving back (I tried limp-wristing and choking the gun, neither mattered) would keep the shell in the tube partially/not letting it eject on top of the carrier fully. The bolt would then lock back, the round would be on top of the carrier, and the weapon would be out of the fight for the last round in the mag. With the SRM spring this problem occured even using 2.75" shells. The M4 spring limited it to hotter 3" magnum loads The M1 spring fixed the issue. Again, a 7-shot tube is a 7-shot tube. Why the M4 has a weak spring and the M1 got a good one is beyond me. I use the good one. As for not fitting enough shells, that is balony. I took the M4 spring and the M1 spring and put them in my old factory extension and then stacked shells on them. There was less than 2mm of difference in the height of the shell column when both were compressed to their physical maximum. Oddly, the M4 spring has more coils than the M1 S90 spring, but it is shorter and of smaller diameter. The only limitation I notice with the M1 spring is that it is more of a PITA to install. Also, they tend to vary from 41-44 coils and a ew " in length (after 100 rounds when they take a set, they all seem to be around 30-32", compared to the M4's 26-28") Benelli will get a call from me, I am curious too. My guess is that most of you who are shooting with the M4 spring and long tube don't shoot 3" magnum buckshot or HEAVY turkey loads. Buy some Remington 3" magnum #4 buck and try it on the last 2 rounds with your M4 spring and report back. I am curious!

If your M4 accepts them and you have NOT BEEN using them, then maybe you can't anymore, as you will quite possibly have royally buggered the threads where the choke installs by now.

Duggan hit it on the head here. Want trumps need EVERY TIME. Period. If it were not true, there would be no sports cars. There would be no golf courses, no resorts, no holidays, and a lot of creativity would be lost. There would be no www.benelliusa.com either, and you wouldn't have an internet connection to access it from if there were...if WANT did not trump NEED at some point.

Mine feels about like a mil-spec AR type trigger. No issues here. It's a shotgun, not an M24.

I have had my M4 turn into a jam-o-matic using the M4 spring and firing heavy loads. I did not buy an M1 S90 spring for fun. I bought it because it fixed a problem encountered when shooting 3" ammunition on the last 2 rounds. It is a 35" spring and the M4 spring is a 27" spring. They both go in a weapon with a 7-shot length tube from the same company. They both have the same tension-per-inch or whatever you want to call it. I believe "spring rate" is the term. I find this VERY odd.

Do you drive an LS2 powered vehicle?

Which Winchester buckshot? I used the OO buck Winchester Supreme XX 2.75" 12 pellet plated/buffered load. At 40 yards through my M4 with a mod choke It will put a minimum of 2 pellets in a 6" circle dead center POA every time. At 25 yards, almost all the pellets are in a chest-size area. Great stuff!

I have owned rifles where the scope cost as much or more than the rifle itself. My Ruger VT .223 was an example. 6.5-20 40mm Leupold VXIII. However, 1/2 MOA at 400 meters was the result, as was a crisp, bright sight picture, edge to edge, at 20X. Here is a good way to separate a decent scope from a crappy one. Look through them both at dusk on the same power setting. 9 times out of 10 you will notice a VERY marked difference in how late in the day you can still make out what you are looking at through either scope. However, some of the cheaper scopes are getting some decent glass and coatings now,and the difference seems to lay in adjustment repeatability and durability of the unit as a whole.

I have used VXIII Leupy's, Nikon Monarchs, and a Gen III Springfield. I have also shot bargain basement stuff like Tasco and Bushnell. The difference is that the nice stuff has ACCURATE and repeatable adjustments, the glass is clear with good, durable coatings, the paralax is easily adjusted out, the very edges of the glass show no distortion compared to the center. Oh, they don't break NEARLY as often either. The US military purchases from the lowest bidder that can meet the spec they set. Now, do you HONESTLY think that your $130 sight couldn't be procured cheaper than the Aimpoints Uncle Sugar is spec'ing? So, there has to be a reason right? I think the reasons I listed above sum it up. Will I ever use it on anything but paper or a deer or something? I hope not. However, that is like never buying anything but FMJ's because I never want to have to stake my life on my handguns. It just isn't smart nor does it belong with the warrior mentality that each person should cultivate. I did not buy a $1600.00 shotgun to put a $16.00 Tru-Glo (or most $130 sights, although the $170 Burris Fast Fire is decent from what I have seen, I just don't like removing the sight to change the battery) on it. I bought it because it was the best, and it is a system, and a system is only as good as it's weakest link, and quite frankly, a $16.00 scope is a heck of a weak link. Kinda wastes the $1300.00 I spent over a used Charles Daley or something.

+1 I can shoot 2-3MOA at 100m with my AR15A2 and Mil-spec ammo, but it takes a LOT longer up close. Same with my Benelli M4 up close. Accurate and does just fine, but it sure ain't quick when I am using slugs. The dot sight will speed up target aquisition a lot for me based on how I perform with an AR.

What optics are you running on your M4? Pictures? I am considering either a Trijicon Reflex II or a Trijicon RX30 reflex. I like the Eotech 552/65 Rev. F as well, but have heard bad things about it's power management (eating batteries/corroded terminals). Also, Trijicon answers their phone. Eotech bounces you between machines of people who "are on vacation but in case of an emergency..." as their primary answering system.

It seems every time I shoot my M4, the magazine spring gets shorter. I realize some "set" is normal, but I am not used to a spring shortening an inch or two after each use. Granted I have not taken it out that much (gone from 35'' to 31" so far), but sooner or later will we reach a status-quo here, or are you guys replacing mag-tube springs at 1,000 or 1,500 round intervals with the extended tubes for reliable function? Is there a standard PM schedual for mag-tube springs on the M4?

Don't you love her ZERO flinch on the empty chamber hammer drop at the end? Sorry, but I had to.

You really do need to toughen up. You are physically capable of it I am sure, work on the mind. It's like me when I first started doing kung fu. I was scared to death of being punched in the face. After a while, it just became the norm. Suck it up and shoot the thing and you will learn to like it, or maybe im just a sick sick man
